BACKGROUND: Nintedanib is a triple angiokinase inhibitor approved with docetaxel for adenocarcinoma non-small cell lung cancer after first-line chemotherapy (FLT). In the phase III LUME-Lung 1 study, overall survival (OS) was significantly longer with nintedanib/docetaxel than with placebo/docetaxel in all adenocarcinoma patients and those with time from start of FLT (TSFLT) <9 months. OBJECTIVE: This study sought to extend analyses from the LUME-Lung 1 study, specifically for adenocarcinoma patients, to explore the impact of clinically relevant characteristics on outcomes such as time to progression after FLT...

The mechanism by which angiogenesis declines with aging is not fully understood. Soluble vascular endothelial growth factor receptor 1 (VEGFR1) form (sFlt1) contributes to endothelial dysfunction in pathological conditions. However, the roles of sFlt1 in ischemia-induced neovascularizationof aged animals have not been investigated. To study aging-related sFlt1 change and its impact on ischemia-induced neovascularization, a hindlimb ischemia model was applied to young and aged mice. Blood flow imaging assay revealed that the blood flow recovery remained impaired throughout the follow-up period...

PURPOSE: We previously showed that intravitreal injection of the sFLT morpholino-oligomer (FLT-MO) suppresses laser-induced choroidal neovascularization (CNV) in mice by decreasing the membrane bound form of Flt-1 while increasing the soluble form of Flt-1 via alternative splicing shift. In this study, we examined whether cyclic RGD peptide (cRGD) can promote morpholino-oligomer accumulation in CNV following tail vein injection, and whether systemic cRGD conjugated FLT-MO (cRGD-FLT-MO) suppresses CNV growth...

The proliferation status of tumor cells can be imaged using [(18)F]fluorothymidine ([(18)F]FLT), which is trapped by cell cycle-dependent thymidine kinase 1 (TK1). Targeting of heat shock protein 90 (HSP90) disrupts multiple client proteins, leading to heterogeneous cell-cycle phenotypes. To investigate whether [(18)F]FLT uptake reflects the growth arrest caused by various mechanisms of HSP90 inhibition, we used HCT116 cells that were arrested at G0/G1 phase, and Hep3B cells at G2/M phase, by the HSP90 inhibitor 17-AAG...

The connection between maternal hematological status and pregnancy outcome has been shown by many independent researchers. Attention was initially focused on the adverse effects of moderate and severe anemia. Interestingly, some studies revealed that mild anemia was associated with optimal fetal development and was not affecting pregnancy outcome. The explanation for this phenomenon became a target for scientists. Hemodilution, physiologic anemia and relative decrease in hemoglobin concentration are the changes observed during pregnancy but they do not explain the reasons for the positive influence of mild anemia on a fetomaternal unit...

The peptide relaxin has gained considerable attention as a new vasoactive drug, largely through its beneficial therapeutic effects in cardiovascular disease. In this study, we tested the hypothesis that relaxin treatment alleviates systemic vascular dysfunction characteristic of hypertensive diseases of pregnancy. We investigated vascular effects and mechanisms of relaxin action in (i) pregnant relaxin-deficient (Rln-/-) mice with enhanced responses to angiotensin II (AngII) and (ii) arteries pre-incubated ex vivo in trophoblast conditioned media (TCM) to induce endothelial dysfunction...
